i believe all LT1 and LS1/6 come with HE pistons
all the GT and older Cobra mustangs come with HEs

86-92 5.0's used forged trw pistons, that's why they were i kick *** street motor, they will live with a big hit of nos or plenty of boost with a decent tune, hell i know guys that have simply split the bock down the middle before breakinga piston, forged pistons + boost + good tune = long happy life together...

i am aware since i own one

there is one year of fox's that came with HE's though. i believe 92.

i meant to say the NEWER gts, like the sn95 5.0 and the OHC engines.

My bad...oh and it's 93's that had hyper's....no idea why tho...

Yep. 93 and newer stangs both 4.6 and 5.0 were hyper. Before that they were forged. I run the stock hypereutectic pistons in my 97 GT. This motor has 280,000 miles on it and runs perfectly. Compression is 180 all around. I have been running a blower with 10 psi boost for the last 173,000 miles. The car uses 1 quart of oil per 1000 miles currently. I have had some mild detonation a few times but never going all out at 10 psi boost. I think the hypereutectics get an undeserved bad rap. With a decent tune, as I have shown in my case, they are excellent. A bad tune will kill any pistons. All that being said, building a forced induction motor from the ground up, forged are the way to go. They give you a little more room for error. Mustang people running forced induction with stock pistons usually see ringland failures if they detonate under boost. For my turbo car, I used forged pistons in the 5.0.

whats the compression on your 5.0? is it stock compression? whats the psi in each cylinder?

i gotta agree with alot of what is being said. Hyper-eutectic's are infact stronger than a cast piston, yet are also infact weaker than a forged one. I believe Forged and Hypereutectic pistons are about the same price. If I'm not mistaken, Hypereutectic pistons are able to be used with non-forged rods, which makes them a nice choice to guys with a low budget. In this case though, it dosen't benefit us honda guys since rods give out at about the same point our ring lands do! I do know that alot of muscle car guys run Hypereutectic pistons in their muscle car's(namely the Keith Urban's).

then what did my 92 have

90dx

So does anyone make Hypertectic pistons for Hondas?

J-SMITH69

wow i forgot to hit post so i'll do it again

1. HE pistons are cast
2. HE pistons are WAY cheaper than any forged peice, sometimes less then OEM replacements
3. since when did forged pistons have to have forged rods attached
4. keith urban is a country singer
5. Keith Black makes HE pistons
